“…When moist grain is fed by weight or volume, the higher water content should be taken into account. In addition, a vitamin E supplementation at a level of 30 mg/kg feed is recommended (Frape 1986), because propionic acid treatment of moist grain resulted in distruction of vitamin E (Rice et al 1985). Further, metabolism of propionate requires vitamin 812, B 12 , the lack of which causes an accumulation of propionate, depressing appetate (Frape 1986).…”

Use of oats treated with propionic acid in horse feeding was investigated in a 48-day feeding trial. Twenty horses were divided into a control and an experimental group. Horses in the control and experimental groups were fed with hay and dry or propionic acid treated oats, respectively, according to their energy requirements. The influence of the diet on health, faecal microflora, haemoglobin and haematocrit values, blood serum glucose concentrations, and weight change was investigated. The state of the health of all the horses was good throughout the trial. The functioning of the digestive tract of the horses was normal, since no symptoms of a declined health status of the digestive tract or harmfull effects on microflora due to propionic acid treated oats were observed. Also the haematology of the horses was unaffected by the diet. These data indicated that propionic acid treated grain can succesfully be included in rations for horses.

“…The other five experimental groups contained either five or six sheep and were designated to be fed on a vitamin E-deficient ration for 1, 2, 4, 8 or 12 weeks before being killed for necropsy. The vitamin E-deficient ration was fed from day 0 and consisted of 800 g barley and 200 g chaff, plus 20 g ground limestone per sheep per d. The barley and chaff had been treated with NaOH by the method of Rice et al (1985) to deplete them of vitamin E. The a-tocopherol concentration in the ration was less than 1 mg/kg (barley 0.6 mg/kg, chaff 2.5 mg/kg).…”

Plasma and tissue concentrations of α-tocopherol during vitamin E depletion in sheep

et al. 1993

To determine the relationship between plasma and tissue a-tocopherol concentrations during vitamin E depletion, weaned lambs were placed on a vitamin E-deficient diet for 0, 1, 2, 4, 8 and 12 weeks. aTocopherol was measured in plasma, erythrocytes, liver, adrenal, adipose tissue, three different skeletal muscles and heart muscle. The a-tocopherol concentration in plasma fell at the same rate as the atocopherol concentration in skeletal muscles, heart muscle, adrenal and adipose tissue. The a-tocopherol concentration in liver and erythrocytes fell at a faster rate than that of plasma and all muscle tissues. There were significant correlations between a-tocopherol concentration in plasma and a-tocopherol concentrations in all the tissues measured. Different skeletal muscles had significantly different concentrations of a-tocopherol which may relate to their differing susceptibility to nutritional myopathy. The increase in malondialdehyde in oxidatively-stressed muscle tissue and the correlation with atocopherol concentration in most muscle tissues indicated that the muscles had reduced antioxidant capacity in vitro as a result of vitamin E depletion. It was concluded that during vitamin E depletion in sheep a-tocopherol concentration in plasma was a good index of vitamin E status under the experimental conditions employed. a-Tocopherol : Vitamin E : Nutritional myopathy : Sheep

“…Deficiency of VitE has been observed in virtually all taxa of herbivores. Vitamin E deficiency can develop in herbivores when they are fed hay with a low VitE content, because of late cutting, leaching or excessive storage, leading to oxidation of VitE (Rice et al., 1985). Reductions in VitE from 80% to 90% during the maturation of grasses are common.…”

“…There are various interactions between VitE and Se (Larsen, 1988;Smith et al., 1997; Kessler, 1999) and it may be possible that there are situations where both micronutrients are at or below requirements. For instance, low dietary Se may be a contributing factor to VitE deficiency developing in hay‐fed animals (Rice et al., 1985). The situation may become critical when either of the two micronutrients becomes deficient.…”

Effect of vitamin E supplementation of sheep and goats fed diets supplemented with polyunsaturated fatty acids and low in Se There are situations of low supply of both micronutrients. As VitE is involved in ruminal biohydrogenation of polyunsaturated fatty acids (PUFA) and their protection against oxidation in metabolism, diets supplemented with PUFA may challenge VitE to an extent making recommended supplies insufficient. Twelve goats and sheep each were fed a diet supplemented with PUFA and characterised by low Se and limited VitE contents during the last 2 months of gestation and the first 2 months of lactation. The basal diet consisted of hay and concentrate. Six goats and sheep received extra VitE, while the control groups received no extra VitE. Blood and milk samples were taken. In addition, liver, heart muscle and spleen samples were obtained from the offspring after slaughtering at an age of 8 weeks. No significant changes were observed in serum Se and VitE. A significant increase in serum VitE concentrations between 2 and 4 weeks postpartum (pp) was evident in the supplemented kids. In 4, 6 and 8 weeks pp, the serum concentrations of VitE in the supplemented kids were significantly higher compared to the unsupplemented group. In the kids, VitE was higher in liver of the supplemented groups. There were no significant differences in response to extra VitE between sheep and goat. The kids responded to serum VitE different from that of lambs, as a significant difference was observed between supplemented and unsupplemented animals in the goat kids, but not the lambs. In conclusion, goats and sheep have to be viewed differently and may not be considered alike relating to VitE/Se metabolism and requirements, especially in young animals. received no extra VitE. Blood and milk samples were taken. In addition, liver, heart muscle and spleen samples were obtained from the offspring after slaughtering at an age of eight weeks. No significant changes were observed in serum Se and VitE. A significant increase in serum VitE concentrations between two and four weeks pp was evident in the supplemented kids. Four, six and eight weeks pp, the serum concentrations of VitE in the supplemented kids were significantly higher compared to the unsupplemented group. In the kids, VitE was higher in livers of the supplemented groups. There were no significant differences in the response to extra VitE between sheep and goat. The kids responded in serum VitE different from the lambs, since a significant difference was observed in between supplemented and unsupplemented animals in the goat kids, but not the lambs. In conclusion, goats and sheep have to be looked at differently and may not be considered alike relating to VitE/Selen metabolism and requirements, especially in young animals.
